2-66 Compaq Parallel Database Cluster Model PDC/O2000 for Oracle8i and Windows 2000 Administrator Guide Table 2-8 identifies possible I/O path failure events for active/standby configurations with two or more RA4000/RA4100 Arrays and the failover response, if any, implemented by Secure Path for each failure. Table 2-8 I/O Path Failure and Failover Scenarios in Redundant FC-ALs for Active/Standby Configurations With Two or More RA4000/RA4100 Arrays Description of Failure The active array controller in one RA4000/RA4100 Array fails. The standby array controller in one RA4000/RA4100 Array fails. The Fibre Channel cable connection between the active array controller in one RA4000/RA4100 Array and its Storage Hub or FC-AL Switch is broken. The Fibre Channel cable connection between the standby array controller in one RA4000/RA4100 Array and its Storage Hub or FC-AL Switch is broken. The Storage Hub or FC-AL Switch that is connected to the active array controller in each RA4000/RA4100 Array fails. The Storage Hub or FC-AL Switch that is connected to the standby array controller in each RA4000/RA4100 Array fails. Failover Response Secure Path forces a complete failover to the standby I/O path components, including the standby Fibre Host Adapter in each node, the other Storage Hub or FC-AL Switch, the standby array controller in each RA4000/RA4100 Array, and Fibre Channel cables. None Secure Path forces a complete failover to the standby I/O path components, including the standby Fibre Host Adapter in each node, the other Storage Hub or FC-AL Switch, the standby array controller in each RA4000/RA4100 Array, and Fibre Channel cables. None Secure Path forces a complete failover to the standby I/O path components, including the standby Fibre Host Adapter in each node, the other Storage Hub or FC-AL Switch, the standby array controller in each RA4000/RA4100 Array, and Fibre Channel cables.
